It's GOOD

How many of the world’s top 73 self-made billionaires were in a worse situation than you when they started? Let's go straight to the point: is it possible for most of us to go from zero to billionaire? Yes. This is how.

The fact that this is out of the top 100 in the WORLD is a very important point. The article says "most of us" can "go from zero to billionaire" and I think that is far too big of a generalization to make about the entire world. The political and economic system of a country plays a huge role in an individual's ability to go from zero to superstar. So, while in many places in the world that may be the case, there are still many places in the world where that is not the case (and the US is one of them). I think it's really important to take into account the generalizations one makes about a population, and whether or not those generalizations apply to the audience for the article. I would hate to see this taken as an excuse for the top 1% in the US.
